Substance use disorder treatment completion rates in adolescent inpatients and factors affecting these rates

The objective of this study is to investigate treatment completion rates among adolescents receiving inpatient treatment for substance use disorders (SUDs) and the sociodemographic characteristics, parental attitudes, and psychiatric comorbidities influencing these rates. The sample consisted of 110 adolescents (84 males, 26 females; aged 14–18) diagnosed with SUDs. Structured psychiatric interviews were conducted, and parental attitudes were evaluated using the Parental Attitude Scale and the Family Life and Child-Rearing Attitude Scale. Participants also completed the Multidimensional Scale of Perceived Social Support and the Adolescent Dissociative Experiences Scale. Only 22.7% of participants completed treatment. Those who completed treatment had a later onset of substance use (13.88±1.31 vs. 12.95±1.82 years), shorter duration of use (31.27±15.91 vs. 48.19±21.08 months), and higher rates of ADHD (76% vs. 42.4%) and heroin use (64% vs. 40%). Democratic and involved parental attitudes were associated with higher compliance. Families should be integrated into the treatment process to enhance outcomes, and treatment approaches should be tailored to adolescents’ clinical and psychosocial profiles.
